Multifunctional alcohol detector and alcohol detection method

Abstract

The invention provides a multifunctional alcohol detector and an alcohol detection method. The multifunctional alcohol detector comprises a gas sampling connector used for being connected with a blowing nozzle, a rapid troubleshooting detection sensor, an active expiration detection sensor, a rapid troubleshooting detection air pump, an active expiration detection air pump, a control module and adisplay module. The gas sampling connector is respectively communicated with the rapid troubleshooting detection sensor and the active expiration detection sensor, and the rapid troubleshooting detection sensor and the active expiration detection sensor are respectively communicated with the rapid troubleshooting detection air pump and the active expiration detection air pump. The rapid troubleshooting detection sensor, the active expiration detection sensor, the rapid troubleshooting detection air pump, the active expiration detection air pump and the display module are electrically connectedwith the control module. According to the multifunctional alcohol detector, rapid troubleshooting detection can be carried out while active expiration detection is carried out, detection abnormity can be eliminated by comparing results of the active expiration detection and the rapid troubleshooting detection, and the detection accuracy and the detection efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of alcohol detection, in particular to a multifunctional alcohol detector and an alcohol detection method. Background technique [0002] The traffic police will use two types of alcohol detectors when investigating drunk driving, namely: quick check alcohol detector and breath alcohol detector. Among them, the quick check detection function can be used for preliminary screening of drunk driving suspicions, and cannot be directly used as a punishment for drunk driving If you want to be punished, you need to take an active breath test through a breath alcohol detector. When investigating drunk driving, the traffic police generally use the quick-check alcohol tester for preliminary screening, and then use the breath alcohol tester for active breath testing when they are found to be suspected of drunk driving, which can not only improve efficiency but also ensure the fairness of law enforcement.

Problems solved by technology

However, oral alcohol is only part of the factors that cause abnormal test results (false positives). There are many other factors that can cause abnormal test results.

[0005] Further, the Chinese patent with the application number 201120152280.X discloses a multi-functional alcohol detector, which has both a quick screening function and a breath detection function. In this patent, it discloses Two implementations, wherein, the first one is as attached to the patent image 3 As shown, the air inlet 1017 of the quick inspection function is located outside the mouthpiece and close to the root of the mouthpiece. If the mouthpiece is not removed for quick inspection and detection, it is difficult for the air inlet 1017 to be close to the nose of the tested population due to the existence of the mouthpiece. , it is difficult to draw the gas exhaled by the person under test, and the detection effect is not good

The second one is as shown in the accompanying drawing 7 of this patent. The quick inspection air inlet 207 is located deep inside the mouthpiece pipe. If the mouthpiece is not removed, it is difficult to extract the gas outside the instrument, and the detection effect is even worse. mouth, because the air inlet is hidden deep in the pipeline, the gas in the pipeline is first extracted when pumping air, and it takes a few seconds to extract the gas exhaled by the person under test, and the entire pumping process generally does not exceed 5 minutes. Seconds, the detection effect is not good. Therefore, in this patent, the rapid inspection detection and the active breath detection cannot be detected at the same time, and only one of the two functions can be used.
